I too am a data person and want to know the stats. My last understanding was that Stage IIIC recurrence rate is around 50% for those who receive Herceptin. However, the reality is that there are very few Stage IIIC diagnosis each year and it is a fairly new classification.
The next time I see Dr. Slamon, I will ask him for a current stat. If anyone knows, he will. My goal is to stay one step ahead of the next Her2 discovery. When Dr. Slamon told me there is a lot of hopeful research going on, that gave me hope. I think it is really important all Stage IIIC patients get connected to a top breast cancer oncologist who will know what to do if you have a recurrence.
My story is listed below.
